Haiti’s citizen seismologists helped track its devastating quake in real time
Two scientists explain how citizen scientists and their work could help provide a better understanding of Haiti’s seismic hazards.
- Science & Society
How extreme heat from climate change distorts human behavior
As temperatures rise, violence and aggression go up while focus and productivity decline. The well off can escape to cool spaces; the poor cannot.
- Physics
Windbreaks, surprisingly, could help wind farms boost power output
Wind farm performance could be improved by 10 percent by using low barriers to increase the wind speed directed at the turbines, simulations suggest.
- Climate
The new UN climate change report shows there’s no time for denial or delay
Human-caused climate change is unequivocally behind extreme weather events from heat waves to floods to droughts, a massive new assessment concludes.
- Chemistry
50 years ago, scientists developed self-destructing plastic
In the 1970s, scientists developed plastic that could quickly break down when exposed to light. But that didn’t solve the world’s pollution problems.
- Earth
A new book reveals stories of ancient life written in North America’s rocks
In ‘How the Mountains Grew,’ John Dvorak probes the interlinked geology and biology buried within the rocks of North America.
- Earth
Greece’s Santorini volcano erupts more often when sea level drops
During past periods of lower sea levels, when more of Earth’s water was locked up in glaciers during ice ages, the Santorini volcano erupted more.
- Earth
Dinosaur-killing asteroid may have made Earth’s largest ripple marks
A tsunami created by the Chicxulub impact could have formed giant ripples found in rock under Louisiana, a new study finds.
- Climate
A stunning visualization of Alaska’s Yukon Delta shows a land in transition
Water and ice helped form the Yukon River’s delta. Now, climate change is reshaping it.
- Paleontology
3.42-billion-year-old fossil threads may be the oldest known archaea microbes
The structure and chemistry of these ancient cell-like fossils may hint where Earth’s early inhabitants evolved and how they got their energy.
- Animals
How intricate Venus’s-flower-baskets manipulate the flow of seawater
Simulations show that a deep-sea glass sponge’s intricate skeleton creates particle-trapping vortices and reduces the stress of rushing water.
- Microbes
Missing Antarctic microbes raise thorny questions about the search for aliens
Scientists couldn’t find microbial life in soils from Antarctica, hinting at a limit for habitability on Earth and other worlds.
